Benefits of technology
This patent describes a method for a first communication device to communicate with a second and a third communication device using different wireless communication protocols. The method involves determining the angle of arrival of signals from each device and creating two beam patterns to minimize interference and maximize communication with the different devices. The technical effect is improved wireless communication that reduces interference and allows for more reliable and efficient communication between devices.
Problems solved by technology
This scheme works fairly well when both protocol transceivers are transmitting, but performs quite poorly in the receive mode.
There is often strong collocation interference when Bluetooth and WLAN data are simultaneously sent to a dual operation device.

Embodiment Construction
[0021]FIG. 1 depicts an example communication system 100 in which a primary network device 101 is capable of communicating over a wireless network or networks using multiple communication protocol paths, e.g., using both Bluetooth and WLAN protocols. The network device 101 may be a portable digital assistant (PDA), cellular phone, vehicle, media player, laptop computer, wireless supported desktop computer, gaming system, networking device such as a router, switch, etc., or any other portable computing device. The network device 101 may communicate with any number of devices through various communication paths. In the illustrated example, the device 101 communicates with a remote Bluetooth device 102 through a Bluetooth communication path 104, and with a remote WLAN device 106 (e.g., a wireless access point) through a separate WLAN communication path 108. The device 101 is thus an example of a dual network device. The Bluetooth communication path 104 may be a standard Synchronous Con...

A first angle of arrival of a first signal from a second communication device to a first communication device is determined. A second angle of arrival of a second signal from a third communication device to the first communication device is determined. A first beam pattern for an antenna array is determined using (i) the first angle of arrival of the first signal and (ii) the second angle of arrival of the second signal. The first beam pattern is for communicating with the second communication device. A second beam pattern for the antenna array is determined using (i) the first angle of arrival of the first signal and (ii) the second angle of arrival of the second signal. The second beamforming pattern is for communicating with the third communication device.
